Her Father Hid a Secret Child From Her for Over a Decade — Then She Cut Him Off for Good

It’s one thing to grow up knowing your dad is messy. It’s another to realize he managed to keep an entire sibling hidden from you, then acted like you were the weird one for caring.

In the original post, a mom of two explained why she’s done playing happy family with the father she’s estranged from—and why she’s not lifting a finger to help him stay close to her kids, even if he’s suddenly interested now.

The problem started long before anyone mentioned grandchildren

She says her childhood was defined by confusion and half-truths. Her father had multiple affairs, and instead of separating his choices from his parenting, he blended them together—bringing her around different women without explaining who they were or why they kept appearing in their lives.

Even worse, she later learned that while her mother was pregnant with her older brother, her father got another woman pregnant too. He “paid her off,” signed away his parental rights, and the child was kept a secret from his family. The poster and her younger brother grew up not knowing this person existed.

She describes spending her early years with that nagging feeling that people were keeping things from her—only to be brushed off and told she was imagining it. So when she eventually found out the secret was real, it didn’t just feel like new information. It felt like confirmation that she’d been gaslit for years.

The secret didn’t stay secret for everyone

Time passed, and that hidden child grew up. When she became an adult, the father reconnected with her and built a relationship. That alone might have been complicated but manageable—except the poster learned that other people in the family had known for a long time.

Her older brother, his wife, and her father’s long-term girlfriend all knew about this sibling for more than a decade. They didn’t just “know,” either; they formed relationships with her. Family dinners, conversations, connection—just not for the poster or her younger brother.

She found out only because her mom eventually told her. When she confronted the people who’d kept it from her, their reaction wasn’t remorse or an explanation. She says they shrugged and treated it like it wasn’t her business.

For her, that reaction was the point of no return. It wasn’t simply that her father had made selfish choices. It was that the people closest to the situation had quietly decided she didn’t deserve the truth.

She didn’t even have good memories to fall back on

Some adult kids stay connected to difficult parents because there’s still a thread—some warmth, some core memory, some reason to try. She says she doesn’t have that. Her father has always been emotionally cold and selfish, and she can’t think of a single positive memory with him.

So when the betrayal landed, there wasn’t a foundation strong enough to absorb it. There wasn’t a “but he tried” or “but he loves us in his way.” It was more like: this is who he’s always been, and now it’s just undeniable.

In her telling, she doesn’t miss him. And maybe that’s the cleanest part of the whole mess—because grief is complicated, but relief can be straightforward.

Then her divorce exposed who was really in her corner

If the hidden-sibling revelation cracked the relationship, her marriage ending shattered it.

She divorced her husband after nearly 20 years together. She says he cheated on her with a sex worker while she was pregnant, and he was secretly using drugs. She didn’t describe it as a single bad decision; it read like a double life with her carrying the consequences while pregnant.

And yet, despite knowing what happened, her father, his girlfriend, her older brother, and her sister-in-law continued having a warm relationship with her ex. That detail mattered because it wasn’t neutral. It wasn’t “we’re staying out of it.” It was ongoing friendliness with the person who hurt her, even after she’d drawn a line and rebuilt her life.

Eventually, she decided she was done and cut them off. What stuck out to her was that nobody seemed to care. No one questioned it. No one tried to repair things. They just let her go.

Now they want access to the kids—without dealing with her

She shares two children with her ex, ages 6 and 8. And now, her father and his girlfriend want to stay involved as grandparents.

The way they’re doing it is what makes it feel especially pointed: they don’t come through her. They go through her ex to find out about hockey, soccer, and other activities, then show up to games. When she’s there, they won’t even acknowledge her.

So it’s not a grandparent relationship built on family dinners or making peace. It’s more like appearing in public spaces where the kids are, collecting grandparent points, and keeping her erased from the interaction as much as possible.

She also added an update that makes the request even bolder: they’re now asking her ex about attending sporting events that happen on her custody time—time she pays for—while her ex is asking if he can share the details with them.

That’s the moment where “they want to see the kids” turns into “they want to step into her life again, on her time, on her dime, with her treated like a stranger.”

She isn’t trying to stop love—she’s refusing to manage it

The mom’s stance is clear: she has made absolutely no effort to facilitate a relationship between her kids and her estranged father, and she doesn’t intend to start.

Part of her reasoning is practical. Her kids aren’t sitting around yearning for grandparents; they already have loving grandparents through her mom and their dad’s parents. This isn’t a case of children lacking support and her cutting off their only connection to extended family.

It’s also emotional. She’s not interested in playing middlewoman for people who kept life-altering secrets from her, minimized her feelings, and then chose closeness with her ex after a painful betrayal. If they didn’t show up for her when she needed family most, she doesn’t see why she should coordinate access now.

And the part that seems to sting the most is how one-sided it all is. They want the benefits—photos, games, the “grandparent” label—without the respect of basic acknowledgment, let alone accountability.

Right now, she’s left with a decision that feels unfair no matter what: either keep her distance and risk being painted as the obstacle, or open a door to people who have already proven they’ll walk right past her. She’s choosing the distance, and in her mind, it’s not revenge. It’s the natural consequence of years of being treated like she doesn’t count.
